BICYCLE-LOCK.

SPECIFIUATON forming' part of Letters Patent N o. 704,65 5, dated July 15, 1902. Application filed August l, 1901.l Serial No. 70,522.. (No model.)

To (all whom, zit may concern:

Be it known that l, HENRY W. MORGAN, a subject of the King of England, residing at Lestershire,in the county of Broome and State of New York, have invented certain new and useful Improvements in Bicycle-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the s me.

This invention provides a simple, cheap,

and effective means'whereby one may lock a 'ing the application of the invention.

is a section thereof about on the line X X of bicycle, velocipede, or like machine when left unattended,thereby preventing the unauthorized use of the machine and interposing a check to its pirating.

For a full description ofV the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and drawings hereto attached.

Vhile the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure l is a longitudinal section of the crank-hanger of a bicycle or velocipede, show- Fig. 2

Fig. l. Fig. 3 is a front or end view of the lock. Fig. 4 is an end view of the lock-bolt. Fig. 5 is a detail view of the key.

Oorrespondin g and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

While the invention is specially designed for application to the crank-han ger, it is to be understood that it may be used in connection the plate 5 and hold itin place. A tube G is located within the casing 3 and may be attached thereto or to the crank-hanger 1l, or -it may be loosely fitted within the casing and held therein against rotation, which is essential in order to admit of the in-and-out movement of the lock-bolt 7. The tube (3 is formed with an internally-threaded opening, the threads matching the threads provided upon the exterior of the lock-bolt 7. The plate 5 closes the outer end of the casing 3 and retains the lock-bolt and internallythreaded tube 6 in place and is formed with a keyhole 8 in line with a slot 9 in the outer end of the lock-bolt 7. The plate 5 is adapted to turn freely in the casing, so as to admit of rotation of the lock-bolt to effect a longitudinal movement thereof. The key 10 is .crimped throughout its length and the opening 8 and slot 9 correspond to the shape of the crimps of the key to admit of the latter being placed in position when it is required to operate the lock-bolt. The shape of the crimps of the key and the form of the opening 8 and slot 9 Will'vary, so that each lockL will require a special key, thereby preventing the opening of two or more locks by one key.

W'hen it is required to lock the bicycle or like machine, the key 10 is inserted through theopening 8 and fitted into the slot 9 and is turned to rotate the lock-bolt and project it into the path of the part l, thereby preventing rotation of the crank-shaft. By turning the lock-bolt in the reverse direction it is moved outward and clears the ostanding part l, thereby permitting the crank-shaft to turn freely. By locating the lock as set forth it is out of theway and occupies a minimum amount of space and is durable and effective for the purpose designed.

As clearly indicated in Fig. 2, the lock is located in the angle formed between the front and rear reach-bars of the frame, hence is out of the Way and protected from injury, and being arranged on the top side of the crankhanger is readily accessible for operation.

Having thus described the invention, what is claimed as new is- In a bicycle or like machine, and in combination with the crank hanger and crankshaft, locking means located in the plane of IOO the frame and Comprising a pin fitted in a l jecting the lock-bolt into the path of an eX- transverse opening of the crank-shaft and having its end portions extended, a easing secured to the crank-hanger in the angie 5 formed between the front and rear reach-bars, an internally-threaded tube secured Within the easing, a lock-bolt having screw-thread connection with the said tube, and a plate rotatably fitted in the outer end of the easingr Io and having a keyhole in line with the said lock-boit for the insertion of a key for pro-
